To all whom it may con-cem.'

Beit known that I, EDWARD C. Woon, of

Somerville, in the county of Middlesex and State of Massachusetts, have invented certaln new and useful Improvements in Emulsiiers, of which the following'is a specification, referencebeing had to the accompany- -ing drawings, forming part thereof.

, constituents 0f milk or other Huid are intimately mixing the constituents of the milk mately mixed to homogenize or emulsify the same.

The principal object ofthis invention is to improve thev construction of machines of this nature whereby the process of intior other liquid may be carried out expeditiously and economically.

Other objects of the inventlon will appear frmn the following description.

The invention consists in certain peculiar features of construction and combination of partsas shall, hereinafter bemore fully described and pointed out inthe claims.

"in vertical section, taken on lines 3-3 Figs.

, and the large gear 18, Fig. 1, which is driven Vwhich valve seat 47, has t from the small gear 14, of the main shaft 15,

' journaled in bearings in the frame 16 mounted on the base 5, and having the pulleys 17 and 18.

Frame 16 is securely fastened to the base 5, and has the vertical member 19, furnished with the guides 20, 21 and 22, and the upper horizontal member 23, furnished with the bolts 24, 24 the lower ends of which are secured in the base 5. In the guides 20, 21 and 22, are slidably mounted the blocks 25,

26 and 27, to which motion is imparted by the rods 28, 29 and 30, of the frames or straps 3l, 32 and 33, embracing, respectively, the eccentric cams 10, 11 and 12, which latter'are so related, as to their throw, that said blocks 25, 26 and 27 are operated in succession whereby the pistons 34, 35 and 36, fixed to said blocks 25,26 and 27 are similarly operated in the bores of their respective pump cylinders 37,38 and 39, which extend through openings in the frame member 23, and are secured to said member by bolts,v

The pump cylinders 37 38, 39, are practically similar in construction as regards the channels for conveying liquid to and from the bores of said cylinders and the valves which control the flow of liquid to and from` said bores; the general construction of said supply channels and their valves, and the connections between said channels will therefore be first described and the more important attachments or modifications appertaining to the respective pump cylinders wlll then be pointed out.

Communicating with the upper end of each of the vertical bores of the pump cylinders 37, 38 and 39, is the horizontal channel 40 which intersects the vertical valve chamber 41 and extends to the face `of the casting 42 at which endit is closed by the plug 43. At their `lower ends the valve chambers 41 have branch channels 44 whlch communicate, at'the face of the casting42,

with the respective branches of the general n supply pipe 45 to which the liquid to be treated is delivered from any source but preferably through the strainer chamber 46, Fig. 1. In the valve chamber 41 are secured the valve seats 47 and 51 spaced apart, of e perforations 48, 48 and is furnished with the aspiration valve 49 free to move away from its seat 47 and having the, stem 50 movably received 1n the bore 52 of the valve seat 51 which seat has the perforations 53, 53 and is supplied with the valve 54 having the stem 55 which is free to move in the bore 56 of the .screw plug 57 by which the upper end of the valve chamber is closed. In order to supply an exit for air, which is drawn into the machine under operation, the bore 56 of said plug 57 extends through the plug 5.7 and intersects the transverse channel 58 which communicates with the annular channel 59 of said plug 57 which is in line withthe channel 60, of the casting 42, from which i let 61;' 61 of all the valve chambers.

the air, and viiuid escaping with the air, is conveyed by the pipe 61 to some suitable receptacle which forms no part of the present invention. Ordinarily the bore 56 is closed by the screw valve 62 having a conical end which is seated in the bore 56 below the channel 58.

Communicating with the upper portion of the valve chamber 41 of the cylinder 37 is the 'channel 63 with which is connected the fitting 64 having the axial assage 65 and the branch channels 66 and 6 the former of which is connected by the pipe 68 with any suitable pressure gage while the latter, ildicated in Fig. 4, connects with the air qqlte closing of the passage 65 from the channel 67 is effected bythe screw valve 70 havingn *an end adapted.- to be seated against a shoulder formed in the lwall of passage 6.7.

lValvechamber 41 of the cylinder 39 has at its upper portion the channel 71 which communicates witha pressure relief valve of any suitable construction and lndicated -in the' drawings as a whole by numeral 72.

The casting of which cylinder 38 formsv part has at its upper end the laterally extending lchamber 73 which is connected by i let of the chamber 73 to which the delivery the passage or duct 74 with the upper vportion of the valve chamber 41v of said cyl- `inder 38. In said chamber 73 is mounted the plug 75 having a bore furnished at its inner end with the conical seat 76 and with. the restricted channel 77, communicating lWith the 'passage 74, and the internaland external clrcumferent-ial grooves l78 and 79 connected by` the ducts 80, 80, andlocatedk approximately in line'with the branch out-l pipe 81 is connected'.` In the bore of plug 75 is mounted the block or valve 82 which is preferably .formed of agateor other hard :material and has an end shaped to conformf to the seat 76 and the stem 83 extending into the passage 74. Pressure is applied, to press said blockloryalve 82 against vits seat 76, by means of the plunger 8 4 which is slidable in the bore of plug 75 and is pressed y inward by the 'spring 85 bearing agalnst the enlargement 86 of said plunger 84 andagainst the frame 87 which is securely' mounted onthe chamber 73. This frame 87 has in its end a screw threaded bore in y .The upper portion of 'the-valve chambers l41, 41 of the cylinders l37 and 38, 39 and 38 are connected respectively by the fpipes 91 and 92 so that llquid may pass rom` the valve chambers of both 'of the cylinders 37 and 39 to the upper art of the valve chamber 41 of the cylin er 38 which therefore forms a central receptacle for liquid to which pressure`may be applied by the up?` ward movement of any one Vof the pistons 34, 35 or 36 either directly, by' piston 35, or indirectly by Vpistons 34 or 36 acting on the milk o'r other liquid in their cylinders.

In the downward movement ofthe several pistons' 34, '35 and 36 milk or other liquid is drawn from the supply pipe 45, through the branches thereof, and enters .the lower ends of the respective valve chambers 41 then passing through the channels 48 of the valve chambers, liftmg the valves 49, and through thechannels 40 into the bores of the respective cylinders 37, 38'v and 39. On the upwardmovernent .of the pistons 34, 3 5 and 36 the milk or other liquidvis forced from ythe bores of said cylinders 37, 38 and 39 back through the channels 40 and, with the contents ofthe valve chambers 41 above the' valves 49, passes through the channels 53 lof i `the valve 4seats 51 to the upper ends-of said valve chambers 41. From the valve cham- :bers 41 of. the cylinders 37 and 39 the milkor liquid passesthrough the pipes 91 and 92 to .the upper portion of the corresponding valve chamber'41 of the cylinder 38.

Under the pressure exerted on the milk or other liquid in the upper portion of said valve chamber' 41 0f cylinder 38, by or through the operation of thepistons 34, 35 and 36, said mllk or liquid is forced through the channel 74, Fig. 2.and intolthechannel 77 of plug 75 where the stream of milk or liquid passes as a thin annular sheet between thestem 83 of the mixing block 82 and the wall of said channel 7 7 and 'then between the conical seat 76, of said plug 7 5, and the com- Inilk or liquid is subjected to great pressure plemental -face'of the block 82 where the' and the globular, or fat carrying particles thereof are disrupted and their constituents are intimately mixed withv the liquid in which they are carried" whereby a homogeneous liquid is formed.

After passing .between the block 82 and its seat the -milk or liquid enters the inner circumferential groove 78 of the plug 75 `and thence through the ducts 8O to the outer circumferential groove 79 to the delivery pipe 81 by which the product is conveyed to any suitable point.

I am aware of Letters Patent to August Gaulin, No. 756,953, dated April 12, 1904,

f and it, is not my intent-ion to claim herein anything shown or claimed in said patent.
